CONVERTIBLE SLED AND BOAT.

Application filed September 3, 1909. Serial R0. 516.07

Be it known that we, Joser Exsno and Enus l'lxnnomitizens of the UnitedStatesof America residing at Erie, in the county of Red Lake and Stateof Minnesota, have in- 1 vented certain new and useful Improvei l i ll'l.'lll in Convertible Sleds and Boats, of which the following is aspecification.

The object of this invention is to provide a construction of boatinvolving suitable propelling means, and associated with a desirablearrangement of runners and guiding devices, whereby the boat may beconverted into a sled to facil tate travel over snow or ice.

The invention involves especially the mounting of the runners and themechanism for actuating the same whereby they may be u out of operativeposition according to whether or not the boat is to travel through wateror form the body of a sled.

For a full understanding of the invention, reference is to be had to thefollowing detail description and to the accompanying drawings, in whichFigure 1 is a side elevation of a convertible boat and .ll'tl embodyingthe invention; Fig. 2 is a top plan view; Fig. 3 is a transversesect iontaken about on the line 3-3 of Fig. 1; Fig. 4 is a transverse sectiontaken about on the line 4% of Fig. 1, and Fig. 5 is a detail sectionalview showing more. clearly the adjustable mounting of the guiding disksor heelslocated at the front and rear extremitie of the machine.

Throagln ut the l'ollowing detail description and on the several figuresof the drawings similar parts are referred to by like. referencecharacter-z. 1

Specifically describing the invention and the drawings 1 denotes a boatof any suitable coictruction and the rear portion of which is formed atthe bottom v-ith a recess '2 providing a compartnu-nt in v hich theupper portion of a s rew propeller E S isarranged. Th propeller 3 ismounted upon a suitable propeller shaft, which su 'iport'ed in bearing-rl adjacent tothe front '2, the front end of thc litntn'li tkliai lprojecting through the front wall of tin recess 1 into the boat andhaving mounted thereon a gear which any u table i-ianually or mo ordrivcn power mcchani-m may be connected i i l l l I 5 with i 1 in orderto propel the boat through the water.

Beneath the boat 1 are mounted spaced runners (3 of any suitable type,said runners being provided at their front ends with two toothedsegments 7' rigidly attached to the runners in any substantial way. Theteeth of the segments 7 arein mesh with toothed pinions 25 mounted onthe opposite ends of shafts 9 supported transversely in the boat.

The opposite ends of the shafts 9 pass through stalling boxes 10 atopposite sides of the boat 1 and project from opposite sides of the boatin such a manner as to receive thereon the exterior pinions 8 that meshwith the segments 7. Links 11 connect the projecting ends of the shafts9 with the runners 6 as shown at 12 and said shai'ts 9 are adapted to berotated by means of an operating shaft 13 having a turning wheel orhandle H at its upper end. the lower end of thrshaft 13 has a gear 15thereon meshing with a bevel gear 16 on a longitudinal shaft 17supported in bearings inside of the boat. On the front and rear ends ofthe shaft 17 are worms 18 which mesh with worm gears 19 keyed or securedto the shafts 9. At the rear endsthereof the runners 6 are provided withrigid segment brackets 20 with which grooved wheels 21 engage in amanner somewhat similar to the cooperation of the pinions 5 with thetoothed segments 7 at the front portions of the runners. The wheels 21are supported upon a suitable shaft which is connected at its end withthe rear ends of the runners by means of links 23.

In order to direct the movement of the boat or sled it is contemplatedto provide at the front and rear ends thereof guiding wheels "it in theform of sharp edged disks carried by bifurcated standards 25, the upperend of which are supported rotatably in pivoted arm-a 2(3- pivotallyconnected with ;the opposite extremities of the boat. The

wheels 3] are adapted to be. raised and lowered by means of a hand lcver27 located at any convenient place intermediate of the ends of the boat,said lever being connected withbcll crank levers 25, the latter being inturn connected by links with the arms 26.

\Vhen the boat 1 is to be propelled through the water the hand wheel 14is turned so as to rotate the pinions S and cause th segments 7 to movertairwardl thereby ti"' .'.ii

ing the runners with res act to the boat and so that they do not interere with the movement of the latter through the water. then the machineis to travel over snow or ice, however, it is desirable that the runners6 be adjusted so that they assume the position shown in Fig. 1 andwhereb the boat is supported thereon and props led under such Thestandards 25 are freely rotatable on the arms 26 and verticaladjustmenhof said standards to vary the operative position of the wheels24 with respect to the runners 6 may be effected bv means of a nut 29 onthe upper end of eac standard and which has threaded connectiontherewith.

Having thus described the invention, what is claimed as new is:

1, In a convertible sled and boat, the comhination of a hoat-, spacedrunners beneath the same, toothed segments carried by said runners,means connecting the runners with the boat in a pivotal manner, pinionsmounted on the boat to engage the toothed segments for moving therunners into and out of operative position, and means for operating saidpinions.

2. In a convertible sled and boat, the combination of i1 boat, a pair ofsnnced unners beneath the same, links pivotaly connecting
